A Nutritionist On The Common Fruit That's Stellar For Mood Stability

When it comes to brain-healthy foods, you likely don't need to search high and low to find the most beneficial players (in fact, you probably have more than a few at your disposal already).

So, which foods top the mood-boosting grocery list? Well, according to Miller, we should pay more attention to the humble banana. 

Why bananas are great for balancing mood

"They're high in vitamin B6," Miller says, which is necessary for creating the neurotransmitters1 that help your body make serotonin and dopamine—both of which influence mood. In fact, one study showed that low levels of vitamin B6 were associated with depressive symptoms2 in older adults. That's not to say the vitamin is a viable treatment for depression, per se, but a deficiency seems to have an effect. 

"They also provide tryptophan, which is fantastic for mood stability," Miller adds. Tryptophan, it turns out, also plays a role in creating serotonin, and research shows that low levels of the amino acid are associated with depression3 and anxiety4.

Mood-boosting benefits aside, bananas have their fair share of health benefits: "They have soluble fiber, which is great support for the microbiome," Miller adds (as you may know, any food that's great for the gut is also simultaneously brain-healthy5), and bananas are a good source of magnesium.

Plus, they're naturally sweet, which is why Miller uses a 12th of a banana in many of her baking recipes—a smidgen won't affect the taste too much (just in case you're not in the mood for a banana-flavored treat), but that bit alone can enhance the sweetness of all your baked goods. 

The takeaway

Sure, bananas aren't exactly groundbreaking, but according to Miller, it's time for the vitamin-rich fruit to receive the recognition it deserves.

Bananas have loads of mood-supporting minerals and amino acids that make them a worthwhile addition to your grocery cart. Consider it another excuse to concoct creamy smoothies.
